THOMAS M. MOREWOOLD, or ELIZABETH, EW JERSEY.

NUT-LbCK.

To all whom it may con/Earn:

Be it known that I, THOMAS M. MORE- a wool), a citizenof the United States, and a resident of 135 Westfield avenue, Elizabeth, New Jersey, and whose post-office address is No. 253 Broadway, borough of Manhattan, county, city, and State of New York, have invented certain new and useful Improvements'in Nut-Locks, set forth in the following specification.

My invention relates to nut locks, my

more particular purpose being to provide a looking lever for holding the nut or bolt,

the lever being held orconfined in a pre-: determined position for preventing the nut or bolt from turning and thus becoming drawings, which form a part of this ap-' plication, in which like characters designate corresponding parts, andin which' Figure 1 is a side elevation showing one form of my device, as applied to the fish plates upon a railway track, the locking levers here extending toward each other and being disposed horizontally; Fig. 2 is a section on the line I1II of Fig. 1 looking in the direction of the arrow; Fig. 3 is a section on a line III-III of Fig. 1 looking in. the direction of the arrow; Fig. 4 is a detail plan of the link strap; 5 shows a form of my invention different from that appearing in Figs. 1 to 3 inclusive; Fig. 6 is a detail plan of one of the locking levers appearing in Fig. 5; Fig. 7 is a fragmentary horizontal section showing another form of my device in which the lug is carried by one of the fish plates.

Two rails are shown at 8 and are each provided with a web 9. A pair of fish plates are shown at 10 and are disposed upon opposite sides of the rail web. Bolts appear at l1-12 and each extend through a rail web and the pair of fish plates. Each bolt is provided with a head 13 integral with it and with a nut 14, the latter being revo-c Specification of Letters Patent. Patented Sept. 15, 1914:. Application filed April 27, 1914. Serial No. 834,802.

bolts 1l12 extend. Each link strap is further provided with a slot 17 as may be;

jacent fish plate 10. Locking levers;- are,

shownat 21' and are each provided with a slot 22 of such width as to fit neatly over the adjacent lug 18. Cotter pins are shown {at 23, and extend through holes in the lugs 18. Each locking lever is provided with an enlarged portion 20 having generally the form of an eye and fitting upon the nut 14. T he head 13 of each bolt issimilarly fitted with a locking lever, which for this purpose is provided with aneye 20 as shown,

at the left of Fig. 2.

f The link straps 15 and the locking levers QC-21 are made of sheet metal, the looking levershaving sufficient resilience to enhble them to'besprung out slightly so as to.

disengage the adjacent lugs 18. Each locking lever20 21' is, adapted toserve practically as a wrench, and as such is us'ed to tighten or loosen the nut 14. NVhen the nuts are screwed up tight, the locking levers are brought into such position that the slots register with the lugs 18, the

latterbeing moved slidably along the slot 17, if necessary. As the lugs 18 are slidable relatively to the link straps 15, looking levers of different length may be used in connection with the same link strap.

In order to turn the nut 14 or the bolt engaging the same, its appropriate locking 7 lever is disengaged, by first taking out the cotter pin 23 and then springing the adjacent end of the locking lever slidably away from the link strap. The locking lever may now be used practically as a wrench.

In the form shown in Fig. 5, the bolts are shown at 2425 and are in the same vertical plane. The nuts engaging these bolts appear at 2627 and the locking levers at 28, each locking lever being provided with an enlarged portion 29, formed into an eye, and fitting over the adjacent nut. The link strap appears at 30 and the lugs at 3132these lugs extending through slots in the locking levers and carrying cotter pins 33 for the purpose above indicated with reference to the cotter pins 23.

In the form shown in Fig. 4:, the bolt 34 is provided with an angular portion 35 forrevoluble nut 36 and engaging the latter is the locking lever 37. This locking lever is provided with a slot 38 and extending through this slot is a lug 39, the latter being mounted rigidly upon the adjacent fish plate 10. A cotter pin 40 extends through the lug 39, and normally prevents the disengagement of the locking lever 37 therefrom.

With the exceptions just noted the locking levers 28 and 37, and parts immediately associated therewith have the same function as the locking levers 20-21 and their associated parts.

In some instances I employ a locking lever which extends from one bolt to another. In this instance the locking lever is provided at one of its ends with a slot of substantially the same form as the slot 16 in Fig. 4. This slot is fitted over a bolt, and a nut is screwed up tightly against the adjacent portion of the locking lever. The other end of the locking lever has a hole for fitting upon the nut of the other bolt. By hammering the end of the locking lever this portion is fitted tightly upon the bolt.

I do not limit myself to the precise construction shown, as variations may be made therefrom without departing from the spirit of my invention as set forthin the claims annexed.

What is claimed and what is desired to be secured by United States Letters Patent 1s:

1. A device of the character described Copies of this patent may be obtained for comprising a pair of bolts disposed parallel with each other, a nut engaging each of said bolts, a locking lever carried by each bolt and provided with a straight portion extending outwardly from the bolt, the straight portions extending toward each other and located in a common plane, a strap link engaging said bolts, and means for detachably securing said straight portions to said stop links.

2. A device of the character described comprising a pair of bolts disposed parallel with each other, a nut engaging each of said bolts, a locking lever carried by each bolt and provided with a straight portion extending outwardly from the bolt, the straight portions extending toward each other and located in a common plane, a strap link engaging said bolts, a pair of lugs disposed intermediate said bolts and secured upon said strap link, each of said locking levers being provided with a slot through which one of said lugs extends, and a cotter pin extending through each lug for holding the adjacent locking lever in engagement with the lug.

In witness whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

THOS. M. MOREWOOD.
